KISTI Supercomputing Center has various types of supercomputers that are products of NEC, IBM, Compaq and Cray. As the only supercomputing center in Korea, it provides those resources to the researchers in industries, universities, institutes, and government organizations. We have brought NEC SX-5/8B to replace Cray C90 which we have shut down in the year 2001. The system has PVP(Parallel Vector Processor) architecture just as Cray C90, and consists of 8 CPUs, and its peak performance marks 80Gflops (10Gflops per CPU).

    It has 128GB of memory, and the capacity of the disk after the installation of OS is 2.59TB. We expect IBM p690 to be our major resource: it has SMP architecture, composed of four nodes. Each node has 128 CPUs, and its peak performance points up to 666Gflops, memory of 688GB, and the capacity of disk, 22.939TB after OS has been installed. We have HP HPC160 and HPC320 which we have deployed in order to have them support Cray C90 while it was still operating.

    There are two other HP systems: GS320, SC45. SC45 expecially supports researches in the area of Bioscience/Biotechnology. HPC160 and HPC320 have SMP architecture, and respectively, 4 nodes and 8 nodes. And each node has 4 CPUs, thus having in total, 16 CPUs and 32CPUs. The peak performance of HPC160 is 21.3Gflops, while that of HPC320 is 42.7Gflops. The memory is 16GB and 32GB each. GS320 is a SMP system with 32 CPUs, and 42.7Gflops of peak performance. Its memory is 32GB. SC45 is also a SMP system, which consists of 16 nodes each with 4 CPUs, in total, 64 CPUs.

    Its peak performance is 128Gflops, and has 92GB of memory and 3.002TB of disk capacity after the installation of OS. KISTI Supercomputing Center also has a MPP Cray T3E. Its peak performance is 435Gflops , and has 128CPUs and 128GB of memory. The disk capacity is 3.584TB and it is being on trial by some of our users. For easier and more effective use, KISTI Supercomputing Center is supporting the users by installing the most of the major application software adequate for each scientific area, on the Compaq SMP system.

   KISTI IBM Power5 System, "Gaia", consists of 10 IBM p5 595 shared memory server nodes. Each server node contains 64 Power5 processors running at 2.3 GHz. In total, the 640 processor system has a peak performance of 5,888 GFLOPS with an aggregate memory of 2,8162 GB. Each node is also supported by 73.4 X 16 GB of local disk, for a total of 1,321 GB, and a faster 60 TB GPFS file system. All server nodes are connected by a IBM high performance Federation switch. The Power5 systems run AIX, a scalable UNIX operating system with High Availability Cluster Multi-Processing (HACMP) capabilities.

    Sun Blade 6048 Cluster system, "tachyon", having  a peak performance of 24 TFlops went into production on June, 2008. The compute and I/O nodes are connected via a non-blocking InfiniBand network with a point-to-point bandwidth of 2.5GB/sec (unidirectional speed). Four Blade 6048 compute racks house 188 x6420 compute blades. Each compute node has four Quad-core AMD Opteron 2.0GHz processor and 32GB of memory. Linux based on a CentOS distribution is installed on compute and login nodes. Users will interact with the system via four x4600 login servers.
Resource management for job scheduling will be provided with Sun Grid Engine (SGE)
The storage includes a 130.2TB Lustre file system for scratch directory, 73.2TB SAM-QFS file system for home directory running across 13 x4500 I/O servers, and 4 x4600 I/O servers, and 422TB SL8500 tape storage for date backup and archiving.
